An image forming apparatus includes a cassette attaching section, a media cassette, a loading plate and a first and second ground conducting route. The cassette attaching section includes a media supplying roller for supplying media. The media cassette is attachably and removably installed in the cassette attaching section. The loading plate is mounted in the media cassette and loads the media stacked up in the media cassette. The first ground conducting route makes static electricity discharge from the loading plate to a grounding portion of the cassette attaching section when the media cassette is attached to the cassette attaching section. The second ground conducting route conducts with the media and makes static electricity discharge to the grounding portion when a distance between the media supplying roller and the media is shortened after the first ground conducting route is conducted.
